Power Consumption

Since power consumption is a big deal these days, we ran some simple power consumption tests on our test beds. The systems ran with the power supplies, case fan, video card and hard drive model. To measure idle usage, we ran the system at idle for one hour on the desktop with no screen saver and took the measurement.

When it came to idle power consumption, the AMD Athlon 64 X2 6000+ consumed the more than any of the other processor on a single socket platform that we tested. By enabling AMD’s Cool’n’Quiet feature we were able to go from consuming the most to nearly the least amount of power! AMD really has made strides with idle and power consumption for those that enable Cool’n’Quiet (C’n’Q in the charts) in Windows. AMD’s 65nm Brisbane-based 4800+ processor took the overall lead when it came to having the best power consumption. When it comes to the QuadFX and V8 systems, these dual socket platforms obviously consume more power as they have another power hungry processor to keep running. Another reason for the large jump up is due to the chipsets that the motherboards use on the QuadFX and V8 platforms, so remember not all the Watt increase is due to the CPU alone.

At load the processors performed as exptected with the Intel Core 2 Duo E6750 consuming 165W and the Intel Core 2 Extreme QX6850 using up 235W at full load.
